In general, a refrigerator is provided with a plurality of storage compartments in which the food is accommodated so as to freeze or refrigerate the food, and one side of the storage compartment is opened to store and take out the food.

In addition, recently released refrigerators are provided with a dispenser that allows a user to take out water or ice. In addition, a water tank may be connected to the dispenser device to store the extracted water.

The refrigerator may be provided with an ice making room for supplying water to make ice, and the ice making room may be provided in the refrigerator main body or the refrigerator door.

In addition, when the ice making chamber is provided on the refrigerating chamber side, in order to provide a low temperature environment, the ice making chamber should be formed to be insulated from the outside. In addition, a flow path may be formed at a side of the ice making chamber and a side of the refrigerator to allow cold air of the freezing compartment to be introduced or discharged.

In the ice making chamber, an ice tray may be provided in which water supplied is made of ice by receiving cold air. In other words, the ice tray may be supplied with cold air in a state where water is filled to form ice.

On the other hand, according to the conventional ice-making chamber structure, the cold air supplied into the ice-making chamber flows in the lateral direction of the ice tray, so that ice making is not smooth and thus the amount of ice making is reduced.

In addition, when ice is manufactured using the cooling core, conventionally, there is a problem in that cold air is not directly transmitted to the cooling core, which is disadvantageous to ice making. In addition, the cooling core positioned far from the cold air discharge port for supplying cold air into the ice making chamber has a problem in that a relatively high temperature is formed and the size of the ice is uneven.

The present invention has been proposed to solve the above problems, and an object of the present invention is to provide a refrigerator in which cold air is efficiently supplied into the ice making chamber by improving the structure of the ice making chamber provided in the refrigerator door.

In addition, an object of the present invention is to allow the cold air supplied into the ice making chamber to flow in the direction of the cooling core to form the temperature of the cooling core at a low temperature, thereby increasing the amount of ice making.

In addition, an object of the present invention is to provide a cooling core in which a uniform temperature is formed in the ice making process by allowing cold air to be supplied downward from an upper portion of the ice making chamber.

In the refrigerator according to an embodiment of the present invention for solving the above problems, a main body portion is formed in the storage compartment; and a refrigerator door rotatably coupled to the main body portion; and provided in the refrigerator door, ice And an ice maker configured to manufacture the ice maker; and an ice maker provided inside the ice maker and having a first cold air inlet formed therein; and a cooling core arranged vertically in the ice maker and cooled by the cold air; And an ice tray configured to accommodate at least a portion of the cooling core therein, wherein the first cold air inlet is provided above the cooling core.

In addition, the refrigerator according to an embodiment of the present invention includes a main body portion in which a storage compartment is formed, a refrigerator door rotatably coupled to the main body portion, and an ice maker provided in the refrigerator door and having a cold air inlet formed therein. A cooling core arranged inside the ice maker and cooled by cold air; And an ice tray arranged under the cooling core, wherein ice is produced, wherein the cold air flowing through the cold air inlet flows from the upper side of the cooling core toward the lower side of the ice tray.

According to the refrigerator having the above configuration, by supplying cold air from the upper side of the ice making chamber provided in the refrigerator door, there is an advantage that the cold air is directly supplied toward the plurality of cooling cores.

Accordingly, since the cooling core is kept at a low temperature capable of ice making, there is an effect that the amount of ice making can be increased.

In addition, since the cold air is uniformly delivered to the plurality of cooling cores, there is an advantage that the size of the ice to be made can be uniform.

In addition, the cold air flow passage 160 extends toward the upper portion of the ice maker 140, and at one end of the cold air flow passage 160, the cold air flow inlet 142 allows cold air to flow into the ice maker 140. Is formed.

That is, the cold air inlet 142 may be formed at the upper portion of the ice maker 140, and the cold air introduced through the cold air inlet 142 may flow from the top of the ice maker 140 toward the bottom thereof.

In addition, the introduced cold air flows through the cooling core 143 to the lower portion of the ice tray 146, thereby cooling the cooling core 143. Of course, the cooling core 143 may be easily heat transfer by the heat transfer fin 147.

On the other hand, on one side of the ice making apparatus 100, a cold air discharge unit 104 for discharging the cold air circulated in the ice maker 140 is formed. The cold air discharge unit 104 may be formed on the same side as the cold air supply unit 103. As described above, the cold air supply unit 103 and the cold air discharge unit 104 may be in communication with the supply duct 22 and the discharge duct 24, respectively, with the refrigerating compartment door 13 closed.

As configured above, since the cool air introduced into the ice maker 140 is supplied from the upper side to the lower side of the ice maker 140, the cold air may directly contact the cooling core 143. In addition, since the cold air may be uniformly applied to each cooling core 143, the temperature of each cooling core 143 may be uniformly formed.

Meanwhile, other embodiments may be proposed.

A second cold air inlet may be formed above the cold air discharge unit 144. That is, if the cold air inlet 142 is regarded as the first cold air inlet, another second cold air inlet may be formed at one side of the ice maker 140.

Therefore, the cold air supplied through the supply part flows through the cold air flow path 160, at least a portion of the cold air flows through the cold air inlet 142, and the remaining cold air is in the ice maker through the second cold air inlet. It may be introduced inside.

By the above configuration, since the cold air is introduced through the plurality of cold air inlets, not only the cooling core can be properly cooled, but also one side of the ice tray can be cooled by the cold air introduced through the second cold air inlet. There is an advantage.
